Excelfore Corporation
Excelfore Corporation is a Fremont, California software company that builds the connectivity layer for software-defined vehicles. Its flagship eSync platform delivers secure over-the-air (OTA) updates and bi-directional data pipelines between the cloud and every electronic control unit inside a vehicle, while its in-vehicle networking stacks (Automotive Ethernet, TSN/AVB) and eDatX data-aggregation and edge-AI products round out an end-to-end cloud-to-edge toolkit. Founded by the brothers behind MARGI Systems, Excelfore helped create the industry-wide eSync Alliance and today has technology deployed across more than 17 million vehicles worldwide.
Ethernovia
Ethernovia is a San Jose semiconductor company building a new class of high-performance automotive and edge packet processors, Ethernet PHY transceivers and switches in 7nm. Its chips act as the deterministic 'nervous system' for software-defined vehicles and physical-AI machines, scaling from 1 Gbps to 10 Gbps to move sensor and compute data with low latency and low power. Founded in 2018 by veterans of Aquantia, the company has raised more than $150 million from backers including Porsche SE, Qualcomm Ventures and AMD Ventures.
Standard Fleet
Standard Fleet is a San Francisco-based software company building a hardware-free fleet management platform for the connected-vehicle era. It plugs directly into a vehicle's own cloud API to deliver telematics, digital keys, automated payments and EV management across 30+ automakers - no dongles or aftermarket devices required. Started as a consumer app for Tesla owners, it now connects roughly 100,000 EVs for rental, rideshare, leasing, insurance, corporate and government fleets, and was the first third-party app authorized on Tesla's fleet platform.
AXONNE
AXONNE is a fabless Silicon Valley semiconductor company building high-speed Automotive Ethernet connectivity for the software-defined, AI-defined vehicle. Founded by ex-Marvell engineering leaders, it designs PHY transceivers and bridge chips - led by its Cyton PHY implementing IEEE 802.3ch Multi-Gigabit Automotive Ethernet - that move 1Gbps to 10Gbps over a single twisted pair or coax, wiring cameras, radar and lidar into the compute clusters that drive ADAS and autonomous systems.
Terraline
Terraline is a Bay Area vehicle technology company founded in 2021 (originally Solo Advanced Vehicle Technologies) by ex-Tesla and Waymo engineer Graham Doorley. It set out to decarbonize freight with a clean-sheet, battery-electric Class 8 long-haul truck, the Tangra LH1, boasting 500+ miles of range and the lowest drag coefficient of any Class 8 truck. The company has since evolved toward a software-defined vehicle (SDV) platform - a central compute system, cloud telemetry, and an AI backend - aimed at modernizing the electronic architecture of heavy machines.
Sonatus
Sonatus is a Sunnyvale-based automotive software company building the AI-powered, software-defined vehicle. Its Digital Dynamics platform - including Sonatus Updater, Automator, Collector AI, and AI Director - lets automakers deploy, monitor, and update vehicle software and edge AI models without rewriting code. Sonatus technology is in production in over 6 million vehicles, including models from Hyundai, Kia, and Genesis.
